Simple Remote Shared Object with Red5 Flash Server

Question

Hello,

I am trying to create a simple chat client using the red5 media server, but I seem to be having a slight hiccup. I am creating a shared object on the server side, and it seems to be creating it successfully. However, when I make changes to the object via the client (type a message), the SYNC event fires, but the content within the shared object remains empty. I suspect I am doing something wrong on the java end, any advice?

Console Results:

Success!

Server Message: clear

Server Message: [object Object]

Local message: asdf

Server Message: change

Server Message: [object Object]

Local message: fdsa

Server Message: change

Server Message: [object Object]

Local message: fewa

Server Message: change

Server Message: [object Object]

Answer 1

you don't need to write anything on the server side in order to do a chat in as3 and red5;

here is an example for you the chat that it is working and it is written in as3/flex3

Answer 2

Yes its posible to create a chat without writing server side code but i dont see how someone could control users disconnections or use lists of users on sync, anyway back to the subject maybe you have a problem with dir permissions so try running red5 as root/admin once , just to check if it works, if it does you should create a user (with the correct writing permissions) in your system and then run red5 using that user.
